Around 2:00 a.m. on a winter morning, Police Officer Clifford Vanterpool responded to a radio dispatch call to check out a suspicious vehicle at an apartment building. As Officer Vanterpool turned his marked police vehicle into the building's parking lot, he saw two people fee from a car, leaving at least one of the car doors open. The driver then began to back out of the parking space. Officer Vanterpool parked directly behind the car, left his own vehicle, and ordered the driver, R. W., to put his hands up. Largely based on evidence found after Officer Vanterpool stopped R. W., the District of Columbia charged R. W. (a minor at the time) with several offenses related to his impermissible use of the car. R. W. moved to suppress the evidence obtained after he was stopped. The trial court denied R. W.'s motion, concluding that the officer had reasonable suspicion to stop R. W. After a bench trial, the trial court adjudicated R. W. delinquent on all counts and assigned R. W. to one year of probation. On appeal, the District of Columbia Court of Appeals reversed the denial of the motion to suppress and vacated the delinquency adjudication. The court held that Officer Vanterpool had violated the Fourth Amendment by stopping R. W. without reasonable suspicion. The District of Columbia sought certiorari. Held: Because Officer Vanterpool had reasonable suspicion to stop R. W., the judgment of the District of Columbia Court of Appeals is reversed, and the case is remanded. When an officer makes a “brief investigatory sto[p] of persons or vehicles that fall[s] short of [a] traditional arrest,” the Fourth Amendment “is satisfied if the officer's action is supported by reasonable suspicion to believe that criminal activity ` “may be afoot.” ' ” United States v. Arvizu, 534 U. S. 266, 273 (quoting United States v. Sokolow , 490 U. S. 1, 7). In assessing whether an officer had reasonable suspicion, a reviewing court must “look at the `totality of the circumstances' of each case”—an analysis that precludes the “evaluation and rejection” of “factors in isolation from each other.” Arvizu, 534 U. S., at 273–274. Reasonable suspicion “ `depends on the factual and practical considerations of everyday life on which reasonable and prudent men, not legal technicians, act.' ” Kansas v. Glover, 589 U. S. 376, 380 (quoting Prado Navarette v. California, 572 U. S. 393, 402). Page Proof Pending PublicationPage Proof Pending Publication
In this case, the information available to the officer strongly suggested that R. W. was engaged in unlawful conduct. The appellate court below reached a different conclusion by “excis[ing]” facts from the analysis, and considering only “the lateness of the hour and the slight movement of the car.” In re R. W., 334 A. 3d 593, 597. That approach is incompatible with the totality-of-the-circumstances inquiry required by the Court's precedents. Based on everything the officer observed on the night in question, he drew the “commonsense inference” that all three people in the car—including the driver—were trying to hide wrongdoing from the police. Glover, 589 U. S., at 381. Certiorari granted; 334 A. 3d 593, reversed and remanded.
Per Curiam.
In the wee hours of a winter morning in Washington, D. C., District of Columbia Metropolitan Police Officer Clifford Vanterpool received a radio dispatch call directing him to check out a suspicious vehicle at a specific address. Officer Vanterpool reached the apartment building at that address around 2:00 a.m. As he turned his marked police vehicle into the parking lot, he saw two people immediately fee from a car, “unprovoked,” after “[p]olice had not done anything other than simply pull up.” App. to Pet. for Cert. 48a. The runners left open at least one of the car doors. The driver then began to back out of the parking space, rear door still open. Officer Vanterpool decided to investigate. He parked directly behind the car, left his own vehicle, ordered the driver, R. W., to put his hands up, and drew his service weapon.
R. W. raised a “single argument” on appeal—that Officer Vanterpool lacked reasonable articulable suspicion sufficient to justify the seizure. In re R.W., 334 A. 3d 593, 599 (D. C. 2025). The District of Columbia Court of Appeals held that Officer Vanterpool, by stopping R. W. without reasonable suspicion, violated the Fourth Amendment. We disagree.

Largely based on evidence found after Officer Vanterpool told R. W. to put his hands up, the District of Columbia charged R. W. (a minor at the time) with unauthorized use of a motor vehicle, felony receipt of stolen property, unlawful entry of a motor vehicle, and operating a vehicle in the District of Columbia without a permit. Before trial, R. W. moved to suppress the evidence obtained after he was stopped. Following a suppression hearing, the trial court denied R. W.'s motion, relying on four facts to conclude that the officer had reasonable suspicion to stop R. W.: (1) the officer had received a radio dispatch call regarding a suspicious vehicle at a specified address, (2) the officer saw “ `two persons feeing from a vehicle' ” upon his arrival, (3) “ `[i]t was almost 2 a.m.,' ” and (4) as the officer approached the car, it began “ `backing out of the parking space . . . while the rear driver's side door [was] still open.' ” 334 A. 3d, at 599. After a bench trial, the trial court adjudicated R. W. delinquent on all counts and assigned R. W. to one year of probation with conditions.

The question is whether the facts available to Officer Vant-erpool—before he ordered R. W. to put his hands up—warranted the stop. In other words, we ask whether Officer Vanterpool had a reasonable suspicion that R. W. was engaged in criminal wrongdoing. Sokolow , 490 U. S., at 7–8. Such reasonable suspicion arises when, based on the “ `totality of the circumstances,' ” the detaining officer had a “ `particularized and objective basis' ” for suspecting criminal wrongdoing. Arvizu, 534 U. S., at 273 (quoting United States v. Cortez, 449 U. S. 411, 417 (1981)). Reasonable suspicion “ `depends on the factual and practical considerations of everyday life on which reasonable and prudent men, not legal technicians, act.' ” Kansas v. Glover, 589 U. S. 376, 380 (2020) (quoting Prado Navarette v. California, 572 U. S. 393, 402 (2014)). It permits officers to make “ `commonsense judgments and inferences about human behavior.' ” Glover,
* The District of Columbia conceded that “Officer Vanterpool seized R. W. when he first asked R. W. to put his hands up,” so the D. C. Court of Appeals decided only “whether the facts then known by Officer Vanterpool created an objectively reasonable suspicion that criminal activity was afoot.” 334 A. 3d, at 599 (citing Terry v. Ohio, 392 U. S. 1, 21 (1968)). Page Proof Pending Publication Page Proof Pending Publication
On the facts of this case, Officer Vanterpool clearly had reasonable suspicion to stop R. W. Already on alert from the late-night dispatch call about a suspicious vehicle, the officer observed every person in R. W.'s car respond strangely to an approaching police car. Two people took off running. We have observed that “unprovoked fight upon noticing the police . . . . is certainly suggestive” of wrongdoing. Id., at 124. The driver, R. W., did not run from the car, but his companions' fight cast his presence in a suspicious light. After all, we have observed that “ `a car passenger . . . will often be engaged in a common enterprise with the driver, and have the same interest in concealing the fruits or the evidence of their wrongdoing.' ” Maryland v. Pringle, 540 U. S. 366, 373 (2003) (quoting Wyoming v. Houghton, 526 U. S. 295, 304–305 (1999)).
We need not determine whether that connection alone supported reasonable suspicion because R. W. was in the driver's seat and—after the passengers fed from the car—began backing out of the parking space, ignoring the car's open back door. For most drivers, it would be a surprising event for their back-seat passengers to exit the car and run headlong away from them. But we doubt that most would respond by putting their car into reverse and attempting to drive away without at least checking whether the doors were closed. R. W.'s own actions—combined with the panicked fight of his companions—strongly suggested that he was (like them) engaged in unlawful conduct he wished to hide from police. See Sibron v. New York, 392 U. S. 40, 66 (1968) (recognizing that “deliberately furtive actions and fight at the approach of . . . law officers are strong indicia of mens rea”).
The D. C. Court of Appeals reached a different conclusion by “excis[ing]” the radio dispatch and the conduct of R. W.'s Page Proof Pending Publication
Page Proof Pending Publication
Indeed, this case reveals the perils of reviewing facts piecemeal and without context. Take the passengers' fight from the car. We have little doubt that, in some circumstances, an officer could not reasonably attribute his suspicion of a feeing individual to bystanders milling nearby. Cf. Ybarra v. Illinois, 444 U. S. 85, 91 (1979) (recognizing that “a person's mere propinquity to others independently suspected of criminal activity does not, without more, give rise to probable cause to search that person”). But the “whole picture” here tells a different story. Cortez, 449 U. S., at 417.
After watching two people fee from a suspicious car, a reasonable officer surely would question the driver's next move. Why would the driver hurriedly back up the car without even closing a car door left open by his feeing companions? Perhaps one could imagine an innocent explanation for such unusual behavior—the court below, for example, surmised that R. W. “may not even have noticed that his companions left the door open.” 334 A. 3d, at 605. “But we have consistently recognized that reasonable suspicion `need not rule out the possibility of innocent conduct.' ” Na-varette, 572 U. S., at 403 (quoting Arvizu, 534 U. S., at 277). Based on everything the officer observed on the night in question, he drew the “commonsense inference” that all three people in the car—including the driver—were trying to hide wrongdoing from the police. Glover, 589 U. S., at 381.
“[T]he Fourth Amendment requires . . . that a court `slosh [its] way through' a `factbound morass.' ” Barnes v. Felix, Page Proof Pending Publication

Dissent — Jackson J.
* * *
The petition for certiorari and R. W.'s motion to proceed in forma pauperis are granted, the judgment of the District of Columbia Court of Appeals is reversed, and the case is remanded for further proceedings not inconsistent with this opinion.
It is so ordered.
Justice Sotomayor would deny the petition for a writ of certiorari.
Justice Jackson, dissenting.
The Fourth Amendment may require courts to “slosh . . . through a factbound morass.” Ante, at 27 (internal quotation marks omitted). It does not require readers of judicial opinions to do the same. Any readable analysis will, of necessity, tick through factors, finding some weighty, others less so, and still others not at all, before piling them on a scale and assessing the result. That is what the court below did Page Proof Pending Publication
Page Proof Pending Publication
To its credit, the Court applies a similar, factor-by-factor approach here. That the Court's analysis is comprehensible shows as much. Like the court below, the per curiam takes account of the facts in turn: a “late-night dispatch call about a suspicious vehicle”; R. W.'s companions' “unprovoked fight”; R. W.'s shift into reverse with a car door still ajar. Ante, at 26 (internal quotation marks omitted). And like the court below, the per curiam explains how much weight it assigns to each. Unprovoked fight, the Court says, is “certainly suggestive” of wrongdoing. Ibid. (internal quotation marks omitted). “[C]ombined” with the fight, the Court continues, R. W.'s abrupt reversal “strongly suggested” wrongdoing. Ibid. This is how courts write opinions.
So I am not sure why our Court sees ft to intervene in this case, let alone to do so summarily. If the intervention reflects a worry that the District of Columbia Court of Appeals (DCCA) misunderstands the Fourth Amendment's totality-of-the-circumstances analysis, that worry seems unfounded. The DCCA has grasped the correct inquiry. Its precedents rightly observe that “[t]he issue is not whether any one factor individually justifies a stop, but rather whether `collectively' the totality of the circumstances supports a determination that the officers had reasonable suspicion for an investigatory stop.” Parker v. United States, 333 A. 3d 1162, 1175 (2025) (citing Mayo v. United States, 315 A. 3d 606, 637 (2024) (en banc)); see also, e.g ., Maye v. United States, 260 A. 3d 638, 647 (2021); Golden v. United States, 248 A. 3d 925, 941 (2021).
If today's decision instead reflects dissatisfaction with the DCCA's comment that it “ `excis[ed]' ” certain factors from its analysis, ante, at 26–27, I do not contest that this was poor word choice, see United States v. Arvizu, 534 U. S. 266, 274 (2002) (rejecting a “divide-and-conquer analysis”). But I do Page Proof Pending Publication
Page Proof Pending Publication
If, finally, the Court's decision to intervene reflects disapproval of the DCCA's assessment of which particular facts to weigh and to what extent, I cannot fathom why that kind of factbound determination warranted correction by this Court. The DCCA assigned no weight to two facts—the dispatch call and the unprovoked fight. The Court does not seem to take issue with the first. For good reason: The DCCA reasonably applied our decisions explaining that an officer may not obtain reasonable suspicion by relying on the unsupported hunch of a fellow officer. See Whiteley v. Warden, Wyo. State Penitentiary , 401 U. S. 560, 568 (1971); United States v. Hensley, 469 U. S. 221, 232 (1985). The Court may be right that the second—the unprovoked fight—should have borne some rather than no weight. But if this context-specific adjustment is all the per curiam seeks to achieve, it does not merit the use of our summary discretion.
Even if I would have assigned more heft to a particular fact in my own first-instance assessment, I would not wordsmith a lower court in this fashion. In my view, this is not a worthy accomplishment for the unusual step of summary reversal. Therefore, I respectfully dissent. Page Proof Pending Publication
